WATCHMANS ELECTRIC TIME-RECORDER.

SPECIFICATION forming part of Letters Patent No. 461,279, dated October13, 1891.

Application filed April 15, 1891. Serial No. 388,98Z (No model.)

To (0Z5 whom it may concern Be it known that I, FRED. W. SOHIEEEE, acitizen of the United States, residing at Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvementsin Watchmens Time-Detectors; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains-to make and usethe same, reference being had to the accompanying drawings, and tofigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in watch mens ti me-detectors, andmore particularly to that class of watchmens time-detectors in whichstation-boxes are arranged at different locations within a building, andas a report is made from any particular station the time of such reportand location of such station is indicated on a dial known as the centralstation, which is electrically connected to all the stations.

Its object is to produce an electrical timedetector for large publicbuildings and factories which cannot be tampered with, is simple in itsconstruction, and records the report made at a station both on a generaldial and at the station itself where such reportis made.

It consists ina series of spring-pressed pins arranged upon a disk,which is made to re- Volvo by electrical connection in such a manner asto present a pin in position to piercea revolving dial operated byclock-Work, there by indicating the station from which the re port ismade and the time of day that such report is made.

My invention further consists in other de tails of its construction, allof which I will now proceed tomore fully describe and claim.

In the drawings, Figure 1 is a front face View with portions brokenaway, of whatI will herein call the central station. Fig. 2 is a rearView of the same. Fig. 3 is a top plan view of the same. Fig. 4 is adetail view showing the arrangement of what I term a reportingstation.Fig. 5 is a top plan view of the same. Fig. 6 shows the generalarrangement of my improvement; and Figs. 7, 8, and 9 are detail views.

Referring to the drawings, 11 is the dial,

which is operated by any well-known clockwork. To the rear of this dialis arranged the disk 12, mounted upon the axle 13. An escapement-wheel14: is also rigidly mounted upon the axle 13, and is operated by theescapement-lever 15, having the lever-arm 16, which in turn is operatedby the magnet 17. On the disk 12 are arranged the short cylinders 18,having pointed pins 1.) passing through them, (a detail of which isshown in Fig. 8,) the pointed ends of the pins facing toward the dial11, (which is preferably made of paper,) but prevented from piercingsame until required by the short spiral springs 20. These pointed pinsand cylinders as the disk 12 is made to revolve pass successively underthe lever-arm 21., having the short projections 22. These short pins orprojections are adj ustably secu red to the T-shaped end of thelever-arm 21 by means of their thread ed'ends, as shown in Fig. 3. Thislever-arm 21 is pivoted, as at 23, and operated by the magnet 24.. Themagnets 17 and 24 are so arranged (as will be hereinafter more fullydescribed) that when a certain station is reported ten distinct currentsof electricity are made to pass through the magnet 17, thus giving acomplete revolution to the disk 12; but as the pin assigned to thestation reported from is directly under the lever-arm 21 then a singlecurrent of electricity is made to pass through the magnet 24, causingthe lever-arm 21 to depress the pin which is under one of itsprojections 22. The pin when so depressed pierces the dial 11, which isso divided by radiating and circular lines that the location of the holemade by the pin will indicate the time of making the report and thestation from which the report was made.

At each station is arranged the crank-lever 25, which when given acomplete revolution constitutes a report. This crank-lever 25 is mountedupon a shaft 26. A coil-spring 27, which is tightened as the crank-lever25 is turned, is attached to the shaft 26, and as the crank is releasedit is brought back to its normal position by the spring 27, which actionis regulated by the gear 28 and escapement 29. Two small wheels or disks30 and 31 are rigidly mounted upon the shaft 26. The disk 30 hasarranged upon its periphery as many pins 32 as there are stationsconnected to the central station, (in this instance I have shown ten,with a corresponding dial.) As seen in Fig. 4, the circuit between thewires 33 and 34 is broken, the wire being connected to any part of thestation, and the wire 34, being insulated as it enters the station, hasits end resting between two of the pins 32. These pins I have numberedsuccessively from 1 to as they pass the end of the'wire 34.

To the disk 31 is secured the Y-shaped pin 36. This pin 36 is placed.upon the disk 31, so as to connect the wire 33 to the wire 35 at such atime as the circuit between the wire 33 and 34 is broken. The pin 36, asseen in Fig. 4, is arranged on a line just beyond the pin 8, which alsodesignates that the reportingstation shown is station 9. Aspring-pressed pin 37 (shown in detail in Fig. 9) is arranged just tothe rear of the gear-wheel 38. This gear-wheel 38 is removably mountedupon the shaft 39 and has an annular groove or recess 40 on its innersurface, over which a paper disk 41 is placed. As the crank-arm 25 isturned the pins 32 on the disk 30 connect the circuit between the wires33 an d 34, and just after the pin 9 has made the ninth connectionbetween the wires 33 and 34'tl1e pin 30 on the disk 30 connects thecircuit between the wires 33 and 35. Before this connection is made,however, the pin 36 on its passage to the wire is made to pass over theinclined surface of the pin 37, which is pressed downward there by andpierces a hole in the paper disk '41 on the gear-wheel 38. As the pin isreleased it is withdrawn from the disk by the spiral spring 42, and ashort auxiliary arm 43, secured to the pin 36, intermeshes with one ofthe teeth of the wheel 38, revolving the wheel and disk sufficiently toreceive the next report. The wire after passing to the battery 44, asshown in Fig. (3, leads from the battery and is divided into twoseparate conductors, one leading to 17 and the other to the magnet 24,and the wires 34 and 35, the circuits of which are broken, (when thecrankarms 25 are in their normal position,) are respectively connectedto the magnets 17 and 24.

The reporting-stations are all of similar eonstrnction to that shown inFigs. 4 and 5, the only diiterence being in the location of the pin 36,which is necessarily arranged on a line between two diiferent succeedingpins of the wheel 30.

Projecting one-half way across the dial 11 and securely held in place isthe plate 45, having the elongated slot 46 just opposite the end of theT-shaped lever 21. This plate 45 serves to hold the dial in place, andat the same time acts as a die-plate for the pins as they pierce thedial.

I claim 1. A watchmans time-detector consisting,

essentially, of a central station having a paper clock-dial mounted uponthe hour-hand of an ordinary clock-movement, said dial being divided byradiating and circular lines, spring-pressed pins arranged upon a disklocated at the rear of said dial, and two magnets, one of which isemployed for revolving the disk bringing the pins in place and the otherfor driving said pins into the dial,a reporting-station to which a wireleading from the two magnets is connected, said wire being so arrangedthat an intermittent electrical connection can be made to one of themagnets, and a signal connection to the other magnet, all arranged andoperating substantially as shown and described.

2. In combination with a watchmans timedetector, spring-pressed pinsoperating within cylinders and located upon a revolving disk, said pinsbeing made to pierce a dial by the action of a lever operated by anelectrical magnet, substantially as and for the purpose stated.

3. In combination with a watchmans timedetector, a disk located at therear of a dial, said disk having pins arranged upon its surface forpiercing the dial at different distances from its center, and anescapementwheel mounted upon the same shaft with the disk and operatedby an escapement connected to an electrical magnet, substantially as andfor the purpose stated.

4. In a watehmans time-detector, a mechanical reporting station operatedby a crank-lever connected to a combination. of wheels and springs, bymeans of which electrical connection is made to a central station, wherethe report is received upon a dial, and a spring-pressed pin arrangedwithin such reporting-station and having an inclined end, over which arevolving arm is made to travel, causing the pin to pierce a disklocated upon a revolving wheel, substantially as shown.

In testimony whereof I have signed m ynanle to this specification in thepresence of two subscribing witnesses.
